Norovirus – a bug that causes gastrointestinal illness – is responsible for 12 percent of all diarrheal disease worldwide and is estimated to cause 218,000 deaths among children under 5 each year.
Now a clearer picture of how this virus spreads and where it originates is being drawn by a review published this week in Epidemiology & Infection.
Norovirus is derived from fecal matter, and can infect people via 4 routes: contaminated water, contaminated food, contaminated environmental surfaces or contact with an infected person.
Researchers from Emory University and the University of Michigan looked at 902 Norovirus (NoV) outbreaks documented between 1993 and 2011, finding that most were associated with transmission through food or in a food service setting.
